Surfactant‐Enhanced Electrospun Nanofiber Filters for Efficient Viral and Bacterial Inactivation
Journal of Applied Polymer Science, EarlyView.In this work, electrospun polyacrylonitrile (PAN) nanofibrous filters functionalized with surfactants (CTAB, CPC, and SDS) were developed for air filtration applications. The PAN nanofiber mats enable efficient particulate matter capture while simultaneously providing antimicrobial and antiviral activity against bacteria (E. coli and S.

Generalized Beltrami flows and other closed-form solutions of an unsteady viscoelastic fluid
International Journal of Mathematics and Mathematical Sciences, 2002 We study flows of an unsteady non-Newtonian fluid by assuming the form of the vorticity a priori. The two forms that have been considered are ∇2ψ=F(t)ψ+G(t), which is known as the generalized Beltrami flow and ∇2ψ=f(t)ψ+g(t)y.

Kolmogorov equations for randomly perturbed generalized Newtonian fluids [PDF]
Mathematische Nachrichten, 2014 We consider incompressible generalized Newtonian fluids in two space dimensions perturbed by an additive Gaussian noise. The velocity field of such a fluid obeys a stochastic partial differential equation with fully nonlinear drift due to the dependence of viscosity on the shear rate.

International Journal for Numerical Methods in Fluids, EarlyView.The proposed work implements a direct flux reconstruction method for spatial discretization and a stiffness‐resilient exponential time integration method for temporal discretization on the cube‐sphere grid. A space‐time tensor formalism is employed to provide a general representation in any curvilinear coordinate system. This combination enables highly
